Until now :

	- Rebuilt interface (slight changes must be made to be full window (not full screen))
	- Added button for Collect Data
	- Added Dropdowns for emotion and data type
Further :
	- Refactor (file opens and closes on each frame read) : could open once at the project start and close at the end of the program
	- Collect Data: write all three type of data at once.
	- Collect Data: save image for each data set (both three types of data collecting).
